Sparc32 - SS5 - TCX-Framebuffer und RTC

[Georg Chini]

Hello,

when compiling 2.6.10-rc3 for my SS5 I have
following problems:

1) TCX-Framebuffer:
    a) drivers/video/tcx.c:
       prom->devname is "SUNW,tcx", not "tcx" in line 469,
       so the framebuffer will not be detected without
       changing that line.
    b) FB-Console does not work:
       When I boot the system with FB-Console I get a blank
       black screen. System boots fine, only nothing is
       displayed.
    c) X will not work in 8-Bit mode:
       Only 32-Bit mode works, maybe this is connected to b)?

2) RTC:
    When compiling with RTC-support I get following messages
    from make image:

   ...

       CC      drivers/sbus/char/rtc.o

     make[1]: *** [arch/sparc/boot/image] Error 1
     make: *** [image] Error 2


Can somebody help me to solve my problems or point me to what to do?

Regards

I'm short on monitors in general so I may need outside help for adequate
testing on the framebuffer issue. I'm also out traveling all this week
so I won't be able to physically reconnect my SS5 until I return.

I've run out of power capacity, terminal concentrator ports, and
intelligently controlled power slots, which is the only reason the SS5's
are disconnected at the moment in the first place.

Before anyone tries to send me one, I should point out that space
footprint is a rather catastrophic issue in my home and I won't be able
to accept any display device with a large space footprint, such as CRT's,
regardless of the fact such originally came with machines of this kind.

I had a similar problem with the cg14 framebuffer, maybe this snippet from
the cg14 fix will help you:

Broken by a recent change in include/asm-sparc/mostek.h, need to include
<asm/io.h> from there now.

Does anyone know if sbus_readb/sbus_writeb should be used there instead of
readb/writeb ?

I'll fix this.

Because it's a byte access, the endianness doesn't matter.  Therefore
the selection between sbus_readb() and readb() is arbitrary so I'll
just leave it alone.
